Over five years, an on-premises server costs far more than the hardware invoice. Add the Windows Server licence and client access licences, a UPS, backup hardware and offsite copies, electricity, the monthly labour to patch and monitor it, and the replacement at the end. In the hypothetical 15-person example below, keeping a file server on site comes to about $34,800 over five years against about $12,000 to run the same files in Microsoft 365 — a gap of roughly $25 per person per month.
That gap is not the whole answer. The line that most often decides it is a line-of-business application: if it only runs on a Windows server, or its hosted version is priced high per user, a server can stay the cheaper option for years. This guide walks through both cost stacks, gives a clearly-labelled five-year table, sets out where each side genuinely wins, and lists the questions that settle it. For context, Statistics Canada found that 48% of Canadian businesses used cloud computing in 2023, up three percentage points from 2021 and the most commonly used technology in the survey.
What an on-premises server really costs
Most quotes show hardware and installation. These are the lines that follow it for the next five years.
- Hardware. The server, its drives, and enough redundancy that a single failure isn’t an outage. Warranty and next-business-day parts coverage are usually separate line items that expire before the server does.
- Windows Server licences. Microsoft licenses Windows Server by physical core, sold in packs, with a published suggested MSRP of US$1,176 for a 16-core Standard licence and US$6,771 for Datacenter. Prices vary by country. Client access licences are bought separately for each user or device, and they’re version-specific: 2022 CALs don’t cover a 2025 server.
- Application licences. Whatever the server exists to run, plus any database licence underneath it.
- UPS. A server that loses power mid-write can lose data. Batteries are consumable and are usually replaced once inside a five-year life.
- Backup. Local backup hardware or software, plus an offsite or cloud copy. The Canadian Centre for Cyber Security recommends the 3-2-1 rule — three copies, two media types, one offsite — with at least one copy offline, and testing restores on a routine basis.
- Electricity. A server runs continuously. At 250 watts, that’s about 2,190 kWh a year, which at BC Hydro’s published Small General Service energy charge of 14.06 cents per kWh is roughly $308 a year before cooling.
- Maintenance labour. Patching, firmware, monitoring, disk space, certificate renewals and the annual disaster-recovery test. This is the line most often left out, and it recurs every month.
- Replacement. Hardware usually outlives its operating system’s support. Extended support for Windows Server 2016 ends in January 2027 and for Windows Server 2019 in January 2029, per Microsoft’s lifecycle dates.
There’s a tax dimension too. The Canada Revenue Agency puts general-purpose computer equipment and its systems software in Class 50, with a 55% declining-balance capital cost allowance rate, and has proposed an enhanced 100% first-year deduction for Class 50 property acquired after April 15, 2024 that becomes available for use before 2027. Cloud subscriptions are ordinarily an operating expense instead. Confirm the treatment for your situation with your accountant.
What the cloud version costs
The cloud stack is shorter, more predictable, and entirely recurring. For a small business replacing a file server, it usually looks like this:
- Storage you already pay for. Microsoft 365 gives an organization 1 TB of SharePoint storage plus 10 GB per licence purchased — about 1,150 GB for a 15-person office — and each licensed user gets their own OneDrive on top of that. Extra SharePoint storage is sold in 1 GB increments per tenant if you outgrow it.
- Licences. Microsoft 365 Business Premium was listed at CAD $29.80 per user per month on Microsoft’s Canadian site as of September 2026, on an annual subscription, before tax. Microsoft’s commercial prices change, so confirm the current figure before you budget.
- Backup. Cloud data still needs backing up. Microsoft sells Microsoft 365 Backup as a pay-as-you-go service at a list price of US$0.15 per GB per month of protected content; third-party services are usually priced per user per month.
- Internet. If the office connection is the only path to your files, it needs to be fast enough and it needs a backup path. A second connection or an LTE failover is a real line item.
- Administration. Less than a server, but not nothing: permissions, sharing policy, retention, licence assignment and the security settings that come with them.
Note the ceiling: Microsoft 365 Business plans are limited to 300 licensed users. Past that you move to Enterprise plans, which are priced differently.
A hypothetical five-year comparison
Assume a 15-person office in one location. Today there’s one physical server running file shares and print services, and the business already pays for Microsoft 365. The server is due for replacement. The question is whether to buy another one or move the files to SharePoint and OneDrive. Microsoft 365 licences are excluded from both columns because they’re paid either way.
| Line item | Replace the server | Move files to Microsoft 365 |
|---|---|---|
| Server hardware, with warranty | $9,000 | – |
| Windows Server licence plus 15 client access licences | $2,550 | – |
| UPS plus one battery replacement | $1,200 | – |
| Electricity, 250 W continuous at 14.06 cents per kWh | $1,540 | – |
| File storage | Included in the hardware | About 1,150 GB included with the licences |
| Backup, local plus offsite ($150 a month vs $5 per user a month) | $9,000 | $4,500 |
| Monitoring, patching and maintenance ($125 vs $25 a month) | $7,500 | $1,500 |
| Setup or migration, one time | $4,000 | $6,000 |
| Five-year total | $34,790 | $12,000 |
The difference is $22,790 over five years — about $4,558 a year, or roughly $25 per person per month. Two assumptions carry most of that result: that the files fit inside the included storage, and that nothing on the server needs a Windows server to run. Change either and the table changes with it. If a line-of-business application has a hosted version at, say, $40 per user per month, that’s $36,000 over five years for 15 people, and the server column becomes the cheaper one.
That’s the real lesson of the exercise: for files alone, cloud usually wins comfortably. For applications, get the vendor’s actual per-user price before you assume anything.
Where an on-premises server still wins
- Specialized or line-of-business software. Accounting, practice management, design, manufacturing, dispatch and laboratory systems often have no hosted version, or one priced well above the perpetual licence you already own. This is the single most common reason a server stays.
- Very large files edited in place. Video editing, CAD and BIM models, GIS data, point clouds and medical imaging move faster over a local network than over an internet connection. Cloud sync can handle them, but the editing experience is where people notice.
- Slow, expensive or unreliable internet. Some industrial and rural sites in the Fraser Valley still have one thin connection. Moving files off site before fixing that is moving the problem, not solving it.
- Contractual requirements about where data sits. Client agreements sometimes specify data location or restrict third-party hosting. Read the contract rather than assuming.
- Licences already paid for. If you bought perpetual licences two years ago, the sunk cost is real even if it isn’t a reason on its own.
- Local devices that depend on it. Door controllers, cameras, machine controllers and some scanning workflows expect something on the local network.
Where the cloud wins
- Hybrid and multi-site teams. With files in SharePoint and OneDrive, working from home is the same as working at a desk. With a server, it means VPN or remote desktop, which is another thing to license, secure and support.
- Growth and contraction. Per-user billing tracks headcount in both directions. A server is sized once, for a guess about year five.
- Resilience. A fire, a burst pipe, a break-in or a failed power supply takes a server with it. Cloud data survives the building. That’s worth more than most of the line items above.
- No capital purchase and no replacement cliff. The end-of-support date stops being your problem, and the budget line is flat and predictable.
- Security tooling. Multifactor authentication, conditional access, device management and data-loss prevention apply centrally, and the audit trail is already there when a cyber insurer or a client asks.
- Office moves. Moving a server is a weekend, downtime and risk. Moving a cloud tenant is nothing.
The hybrid middle ground
Most small businesses don’t land on either extreme. Three arrangements work well in practice:
- Move everything except one application. Email, files and collaboration go to Microsoft 365; a single small server stays for the application that needs it. The server gets smaller, simpler and cheaper, and it stops being the thing everyone depends on every minute.
- Cloud files with a local cache for heavy work. Teams that edit large files keep a small local device for working copies, while the authoritative copies and everything else live in the cloud.
- Lift the server into a hosted virtual machine. The application keeps running as-is, but the hardware, UPS and power lines disappear. This trades capital cost for a monthly bill and is worth pricing before buying new hardware, particularly if the office may move.
Whichever shape you choose, keep an honest inventory of what depends on the server. The migrations that go badly are the ones where a scanner, a label printer or a nightly export nobody remembered turns out to be pointed at a share that no longer exists.
What the move itself costs
Migration effort scales with mess, not with gigabytes. The work is roughly:
- Inventory and clean-up. What’s actually in the file share, who uses it, what hasn’t been opened in five years, and which folders can be archived instead of migrated. This is where the time goes, and it’s work you can do yourself to reduce the bill.
- Permissions mapping. Folder-level permissions on a server don’t translate one-to-one to SharePoint sites and libraries. Deciding the new structure is a business conversation, not a technical one.
- Staged copy and cutover. A bulk copy first, then a final sync over a weekend so nothing is lost between the two.
- Re-pointing what depends on it. Mapped drives, scanners, backups, shortcuts, templates and anything with a hard-coded path.
- Training. Short, practical and worth doing. Most complaints after a file migration are about not knowing where things went.
Two Microsoft limits are worth knowing while you plan: individual file uploads are capped at 250 GB, and Microsoft recommends syncing no more than 300,000 files in a single library for good performance. Our Microsoft 365 migration checklist covers the mailbox and DNS side of the same project, and our backup and disaster recovery guide covers what to put in place afterwards.
The questions that decide it
Answer these before pricing anything
- What runs on the server today — every application, share, print queue, scan destination and scheduled job?
- For each application: is there a hosted version, what does it cost per user per month, and does the vendor still support the on-premises edition?
- How much data is there, how much is active, and how much could be archived instead of migrated?
- How large are the files people edit daily, and over what connection?
- What is the office internet speed, and what happens to the business when it's down for a day?
- How many people work off site, and how do they reach the server now?
- When does support end for the current server operating system?
- What does a full restore look like today, and when was it last tested end to end?
- Is headcount likely to grow, shrink or move locations inside five years?
- Do any client contracts or insurance conditions say anything about where data is held?
If most answers point one way, the cost table will follow. If they’re split, the hybrid options above usually cost less than forcing either extreme.
